So a three tip plug should be fine, if I read that correct, if you short the one ring to ground it acts like a ground. I have a three tip plug but the light is not changing to any input.The Nicrew is 0-10v Analog, quite a few people are using it and they seem to like. @lucasw try changing the PWM frequency for the pca9685 driver to 600 instead of the 150 it's likely set to, this should clear up the flickering.
@Tom Bishop looks like you have things connected correctly, maybe check the ground is actually connected from Pi to ground going to light, if there's no common ground I think you'll have full power and no dimming even if signal voltage changes.
The plug in the Nicrew is actually a TRRS as mentioned, one ring has +24v on it which is used to power the Nicrew controller, apparently shorting out the ring (+24v) and sleeve (GND) you will get a ground that's why the Amazon listing shows a TRS connector.
how so, you got full control of the lights with timers, dimming and spectrum? looking into getting some of these for my 90 there are only 2 channels white and blue so you can control timing and dimming for each of the 2 channels.www.reef2reef.com
